HOWARD M. LEONARD, OF JACKSON, MICHIGAN, ASSIGNOR TO RUBY MANUFACTURINGCOMPANY, OF JACKSON, MICHIGAN.

ROOF STRUCTURE FOR PORTABLE BUILDINGS.

Application filed February 26, 1912.

ToaZl whom it may concern:

Be it known that I, HOWARD M. LEONARD, a citizen of the United States,residing at the city of Jackson, county of Jackson, and State ofMichigan, have invented certain new and useful Improvements in RoofStructures for Portable Buildings, of which the following is aspecification.

This invention relates to improvements in roof structures for portablebuildings.

The invention is especially adapted to roof structures for sheet metalportable buildings, of the knock-down variety.

The objectsof the invention are, First, to provide improvedinterchangeable roof sections and improved means for attaching the same.Second, to provide an improved construction of support for the roofsections. Third, to provide an improved ridge construction. Fourth,toprovide improved cornice construction. Fifth, to provide improvedjoint means between the roof sections.

Further objects and objects relating to economies and details ofconstruction will definitelyappear from the detailed description tofollow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure constituting a preferred embodiment of my invention isclearly illustrated in the accompanying drawing, forming a part of thisspecification, in which:

Figure I is a perspective view of the framework for the roof structure.Fig. II is a perspective view in reduced form, of the roof structurecomplete. Fig. III is an enlarged detail view, partially in section, online 3.3 of Fig. II, showing details of the connection of the roof withthe side wall and the cornice structure. Fig. IV is an enlarged detailin sectional plan, on line corresponding to line 4-4: of Fig. III,showing the corner construction and the connection and relation of theparts. Fig. V is a detail perspective view of one of the corner clipplates. Fig. VI is an enlarged detail sectional view on linecorresponding to line 6-6 of Fig. II, showing the joints between theroof sections. Fig. VII is an enlarged Specification of Letters Patent.

detail sectional view on line corresponding to line 77 of Fig. II,showing the peak or ridge structure. Fig. VIII is an enlarged detailsectional view on a line corresponding to line 88 of Fig. II, showingdetails of the cornice structure at that point. Fig. IX is an enlargeddetail perspective view of the peak or terminal of the roof. Fig. X isan enlarged detail sectional view on line corresponding to line 10-10 ofFig. IX, showing details of construction of the peak ornament orterminal at that point. Fig. XI is an enlarged detail vertical sectionalview through the roof terminal and ridge structure, taken on a linecorresponding to line 11l1 of Fig. XII. Fig. XII is adetail transversesectional view through the ridge taken on a line corresponding to linel212 of Fig. XI. Fig. XIII is a detail cross sectional view, taken on aline corresponding to line 6-6 of Figs. II and III, of a modifiedstructure of roof joint.

In the drawing similar numerals of reference refer to similar partsthroughout the several views, and the sectional views are taken lookingin the direction of the little arrows at the ends of the section lines.

Considering the numerals of reference, my improved roof structure issupported on corner posts 11 and the intermediate posts 2. These partsare connected together by the stringers 3 having lugs 3 for receivingand retaining the side wall structures.

The pairs of rafters A are joined atv their upper ends by plates 5,suitably riveted or bolted thereto. The rafters are made of angle barwhich is notched at 6 and folded downwardly and secured to the posts 1and 2 by suitable bolts ,7, as clearly appears in detail in Figs. IIIand IV. Corner clip plates 9 are interposed between the various parts toretain them securely in position and in alinement.

Side walls made up of plates 10, supported by suitable angle bar frame12, over which the plates are folded, are provided withupwardly-projecting tongues 13 in proximity to the frame, forming agroove to receive appropriate tongue members on the roof sections.Purlin plates 14 made up of L-shaped angle bars secured to the raftersby one limb, the other limb projecting upwardly at right angles to therafter, are

provided with downwardly-projecting retaining lugs on their upper edges,as clearly appears in Figs. I and III.

The roof is made up of identical sections 17 with the exceptions thatthose at the plates are secured to these angle bars by rivets 19, or byspot welding. The lower edge or eaves of each roof section is foldedback upon itself at 20, as indicated.

A tongue piece 20 is secured within the angle of the frame at this pointand projects downwardly into the groove between the flange 12 and thetongue 13, already described, at the upper edge of the side wallsection, clearly detailed in Fig. III.

The roof plates are secured to these angle bar frames 18 and the sidesof the same are turned upwardly at 21 at the meeting edges between theroof sections, and the outer edge is turned up at 34 to give a corniceeffect. Over these up-turned meeting edges, an inverted U-shaped strip22 is fitted and crowded down over the same and is retained in positionby the fastening 23 like a McGill paper fastener, inserted up throughthe same between the frame bars 18 and the upturned edges 21 andexpanded out over the top of the retaining strip 22, as illustratedspecifically in Figs. VI and VII. This makes a very secure roof couplingand one which can be very readily removed. It is a very easy matter tosupply new fastening devices in the event that they become broken orlost.

A ridge piece 24 is provided, folded to suitable ornamental form, eachside 25 of which is extended downwardly at the proper angle and foldedback upon itself, thence downwardly at 26 and thence downwardly andoutwardly at 27 forming grooves or channels into which the upper ends ofthe roof sections 17 fit and are disposed, forming a very secure andsatisfactory joint at that point, which is thoroughly weather proof.

An end ornament or roof terminal 28 of any suitable form is providedwith sleeve 29 to fit over the ridge piece 24 at each end and conformthereto. Each ornament is provided with downwardly-extended flanges 30which close under the projection end cornice forming a secureweatherproof joint at that point and securing a very ornamental eifect.This piece can be formed of a single piece of metal by the use of anappropriate pattern.

The manner in which the end cornice is formed appears clearly from Figs.VIII, IX, X and XI, where the outer edge of the roof section is foldedupwardly at 34 and downwardly and back to the frame 18 at 32. A cornicepiece embraces the same at 34 and extends under at 35 with adownwardlyprojecting flange 37 to engage in suitable grooves on theupper ends of the end panels of plates of the building.

The end of the building is supported'by suitable door posts 38 and isprovided with a cross bar 39 at the top. A collar beam 40 is above thecross bar 39 and cross bars 41 extend between posts 1 and 38. Anattaching plate 42 is provided in the gable. Diagonal brace rods 43extend from corner to corner of the frame.

In Fig. XIII, I show a modification of the roof joint, in which aspecial joint strip is dispensed with and the upturned flanges areconformed to engage the one over the other.

The left-hand flange 44, for instance, being formed by a recurved edgeof the sheet metal plate of the roof section, and the right-handupturned edge flange 45 of the adjacent section being folded into agrooved flange to fit over the same. This distinctly appears in Fig.XIII where the left-hand member 44 is shown fitting into the groovedright-hand member 45 of the adjacent section. This structure is morepermanent than that of the preferred form, but iscapable of separationby opening the grooved member 45 and lifting the sections apart whenthey have been moved along the purlin plates out of engagement with theugs.

Having thus described my improved roof structure, I desire to state thatI have shown it in detail in the preferred form. It is capable ofconsiderable modification without departing from my invention which isclearly defined in the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. In a roof structure, the combination of suitable rafters; purlinplates of angle bar with upwardly projecting ribs secured thereto andwith laterally-projecting lugs on said ribs; roof sections made up ofsheet metal; a frame formed of'angle bars for each of said roofsections, one limb of said angle bars forming downwardly-projecting ribson the under side thereof, the said pro jecting ribs of each frame beingprovided with L-shaped slots to receive the edge and lugs of theupwardly-projecting ribs of said purlin plates to retain the saidsections in place, all coacting substantially as described and for thepurpose specified.

2. In a roof structure, the combination of structure of sheet metalfolded upon itself to form channels at each side for receiving the upperends of the roof sections, and suitable detachable terminals conformedto the ridge structure and fitting over the ridge structure and roofsections and having portions engaging underneath the roof sections, asdescribed.

3. In a roof structure,'the combination of suitable rafters, detachablesheet metal roof sections carried thereby, downwardly-projecting sheetmetal tongues on said roof sections in line with the side walls, andside walls with groove structures to receive said tongues, as described.

In witness whereof, I have hereunto set lbmy hand and seal in thepresence of two witnesses.
